If you have to fly cross country, then by all means hop on a plane.

But, since you're so attuned to facts, you probably know that the vast majority of flights in the US are NOT long-haul, but regional or even short haul flights, and high speed rail from city center to city center is a lot more convenient in most of those cases.

And none of which changes the fact that Boring Co will never, ever, construct an actual "hyper loop".
